Where are marine Ecoregion located?

What is the most diverse marine ecoregion?

Is WWF a database?
The WildFinder application enables users to visualize global distribution of animal species based on the WWF terrestrial ecoregion maps. They can also browse and print ecoregion-based thematic maps. The WildFinder database currently includes four taxa: mammals, amphibians, reptiles, and birds.
What is a marine realm?
Very large regions of coastal, benthic or pelagic ocean across which biotas are internally coherent at higher taxonomic levels, as a result of a shared and unique evolutionary history. Realms have high levels of endemism, including unique taxa at generic and family levels in some groups.
Which is very rich in marine life?
The Persian Gulf is home to over 700 species of fish, most of which are native. Of these 700 species, more than 80% are reef associated. Nevertheless, coral reefs have been found along sections of coast of all countries in the Persian gulf.

What are the Marine Ecoregions of the world?
Marine Ecoregions of the World (MEOW) is a biogeographic classification of the world’s coasts and shelves. It is the first ever comprehensive marine classification system with clearly defined boundaries and definitions and was developed to closely link to existing regional systems.
How many ecoregions are there in the world?
Here we report on a new global system for coastal and shelf areas: the Marine Ecoregions of the World, or MEOW, a nested system of 12 realms, 62 provinces, and 232 ecoregions.
Which is the first comprehensive marine classification system?
It is the first ever comprehensive marine classification system with clearly defined boundaries and definitions and was developed to closely link to existing regional systems. The ecoregions nest within the broader biogeographic tiers of Realms and Provinces.
How are the different marine regions related to each other?
Each of these different marine areas has very distinct hydrological, oceanographic and ecological conditions. Therefore, by combining the information on regional seas and national maritime boundaries, we can include both a environmental and managerial factor.
